Work Text:
They were going to a party and Katsuki had, for whatever fucking reason, agreed to go.
Iida was the assigned driver since 1.) it was his car (specifically his mom’s minivan) and 2.) he knew the dumbasses of class were planning on getting fucked up and wanted to make sure they had fun and weren’t burdened with the responsibility of driving everyone back. His group of idiots had already pilled in, and now they were double stacking in like fucking sardines. He started to make a run for it but stupid Sero ducted taped his waist and reeled him into the van. The noise, the slight smell of sweat, and the dumb faces staring back at him were making his palms sweat dangerously.
“Just sit somewhere! We still have more bodies coming in,” Mina said as she pushed on his unmovable ass at the open doors of the car.
“I’ll fucking kill you,” Katsuki growled over his shoulder.
“Maybe we should go in more than one car, this is highly unsafe!” Iida, always the voice of reason.
“Bakugo! If you don’t move your ass, I’m going back there and putting it somewhere!” That loud ass support course girl yelled from the passenger seat. Fucking girlfriend privileges.
“Bakugo, we do have more people still needing to join, just sit somewhere.” Fucking Glasses, always the voice of DUMBASS.
He looked at the back row. Half-and-Half was sitting on the left (Katsuki’s right) and Katsuki would rather get strapped to the hood of the car like priced cattle. Bird Face was in the middle and that was already a hard pass considering Katsuki was a couple feet taller and had more than a couple pounds on the scrawny kid. And on the right…
“I can take a bus there, actually,” Izuku started to mutter under his breath as he made to stand up but Mina was still pushing Katsuki’s ass further into the car and whatever he was the only option and Katsuki was already halfway in the car and he was the only option so if Katsuki had to sit somewhere –
“Sit your ass back down, nerd.” Izuku obediently stopped shuffling, Katsuki lowering himself on his lap harshly, as if he didn’t give a crap who was underneath because he didn’t. The nerd went rigid beneath him, his legs bracketed by Katsuki’s as he tried to keep his weight on his arms (because Izuku could hold double Katsuki’s weight without even trying but he shouldn’t have to), gripping the headrest in front of him as if he was hanging off a damn ledge (well, in some ways, he was).
The rest of the morons finally got in the car, Frog Girl being the final nail on Katsuki’s metaphorical coffin when she took her seat on Bird Face.
The party was a half-hour drive, another rich kid Third-Year, and the consensus was to pregame the loud music and hollering from the party in the car with their own loud music and hollering. A fucking nightmare.
At some point the effort of trying to keep his weight off the nerd seemed a fight not worth fighting and he had slumped against his sturdy frame. The fucker spent just as much time training as Katsuki did, if he couldn’t handle the weight then what kind of fucking hero was he going to be? Especially his thighs – massive fucking thunder thighs – but they were deceptive, hard as fuck and poking at his right ass cheek. He’d always pictured them softer (NOT THAT HE IMAGINED THEM AT ALL OKAY FUCK YOU).
Glasses, ever the goody two shoes, avoided the highway all together and took back streets since the car was too ‘dangerously filled with future pro heroes’ which just added another 15 minutes to their drive. Fucking fantastic. Taking the back roads also apparently meant taking roads that hadn’t been maintained in a fucking century with the number of potholes they kept driving over.
“Fucker, you trying to give us a concussion?!” Katsuki yelled after a particularly hard shake when they drove straight into a damn pit on the ground.
Support Court just turned the music louder, drowning out Katsuki’s complaining when everyone started screeching the lyrics out. He was gonna kill them as soon as they got to the party, Katsuki swore that on All Might himself.
He leaned back again, pressing harder against the nerd’s chest to take his frustration out on someone, and only then did he notice the tight grip on his waist. The fucking balls on that freckled fuck. Katsuki turned to face the idiot with the rage of a thousand suns but when he saw the pained expression pinching his brows and mouth tight, that rage was redirected.
“OI! Deku you better not be getting fucking car sick!”
That got Bird Face’s and Frog Girl’s attention, the only ones that could hear him over the loud music. They both chimed in their concern, snapping Izuku out of whatever was making him sweat out buckets. “Huh? No, I’m fine, really!” That dumbass smile he gave only when he’d been caught doing something. “I think the sandwich I ate for lunch just isn’t sitting right, but I’m okay!” Convincing enough for the extras to stop questioning him, turning their attention to Half-and-Half and whoever the fuck else. Katsuki didn’t buy it. “Honestly, Kacchan, I’m fine.” It was more strained than the first time he’d said it, wouldn’t even meet Katsuki’s eyes. Coward.
“Nah, I call bullshit. I swear, if you fucking throw up on me – “
Another pothole, another jostling, but now both of Izuku’s hands were harshly gripping on Katsuki’s waist, almost definitely bruising. Katsuki turned to face him again, but Izuku pulled him flush against him before he could. “Stop fucking moving,” Izuku hissed into the small space behind Katsuki’s right ear.
The tone left no room for arguing but even if there had been… Katsuki wouldn’t have said shit. He felt his blood run cold, freezing him in a kind of fear he’d never experienced, not even in his worst battle. Katsuki had felt the growl vibrate from Izuku’s chest straight up his spine, making goosebumps break out over his neck where Izuku was fucking panting against him. His hands were shaking from how hard he was gripping at Katsuki and Katsuki in turn had returned to the lifeline the headrest in front of him had been at the start of the drive, almost ripping it straight out with his white-knuckle grip. A stupid part of his brain, the part still trying to catch up, thought maybe the nerd really was car sick and was about to hurl all over him, but the hard ass boner now nuzzled right in the middle of Katsuki’s ass told a different story.
What the hell else are you supposed to do when your childhood friend, rival turned friend turned maybe crush, fucking NERD shoves his raging boner straight between your ass cheeks in a car filled with their partying classmates? No, seriously, what the fuck are you supposed to do, ‘cuz fuck if Katsuki knows.
Izuku’s fingers twitched where they still rested, loosening just slightly so it wasn’t as crushing, but they were still there, keeping Katsuki nice and still in… what? Shock? Unfamiliarity?
Anticipation?
Tension bled from chest to back, neither willing to make the first move. Hell, Katsuki didn’t know if he was even supposed to acknowledge the, um, fairly girthy elephant in the guy’s shorts. Izuku took the option away from Katsuki.
“I’m sorry, shit,” Izuku breathed out as his nose ran along the shell of Katsuki’s ear, “I swear I didn’t mean to, still don’t mean to. I’m – fuck, I’m so sorry Kacchan, this is so fucked.”
Yeah, very fucked. Katsuki tried to keep his breathing even despite his heart threatening to beat out of his chest. Maybe if he focused on whatever stupid song Pinky and Shitty Hair were butchering in the seat in front of him, his own waking cock would calm the fuck down. Izuku’s heavy breathing against the juncture where his neck meets shoulder wasn’t fucking helping either.
When the idiots in middle school started aggressively hitting on the girls from class, Katsuki had simply rolled his eyes. He got murderous at the thought of possibly having missed puberty but it came and went, and then he was in the best high school in the country and was thankful that he’d never had that damn distraction the rest of the class was stupid enough for. Except for them, it wasn’t a distraction. He was with other rising heroes (and fuck did it feel like pulling out teeth to admit that) and they were doing just fine despite all their free time being spent ogling and bitching about their childish crushes. They were keeping up with Katsuki (as best they could considering they’d never actually catch up to him, let’s be real) while also doing something Katsuki… seemed to be missing. What the fuck?
It hadn’t been an issue, he wasn’t weak enough for those fucking urges to fog up his brain, but just because it hadn’t been then doesn’t mean it wasn’t one now. And it was a fucking ISSUE. Because now he had Izuku’s dick between his damn ass cheeks (which was definitely new) and the beginnings of a boner (an even more terrifying new) and he was frozen in place, completely lost on what the FUCK to do.
The nerd was doing his own breathing counts, trying to calm himself down, and something within Katsuki scratched at that. Did he want Izuku to lose the boner? It fit so perfectly under him, and even though Katsuki was wearing jeans, the cotton shorts Izuku had on left little to the imagination, every twitch noticeable and begging for Katsuki’s attention.
‘A serial killer tapping the window’ kind of attention.
So he focused on the dark road ahead, illuminated by the van’s high beams, Izuku’s ragged breathing still heavy behind his ear keeping his own dick slowly but surely filling and filling and -
Even though he’d been watching the road, it’d been through hazy eyes, his mind blurring the lines between the outside world (the rest of the car) and whatever the hell was happening under him so this time when they hit a pothole, with Izuku’s tight grip steadfast on his hips, Katsuki landed hard on Izuku’s lap, and even he could feel grind with earthshattering clarity. The sharp gasp that earned him was drowned by the idiots cheering, some of them pretending they were on a rollercoaster, completely unaware of Izuku’s downright whine against Katsuki’s neck.
“Kacchan, wait wait hold on wait.” As if he was doing anything. Right now, he was nothing but an ass for the perverted bastard with no space to run, left to just take whatever Izuku wanted to give him.
So why the fuck was he fighting back the urge to run a palm down his crotch?
Izuku rolled his hips, slow but firm as to not draw the attention of the other two sitting inches away from them. It was slow, barely restrained movements, as if Izuku was having a hard time not moving at all. Almost as if Katsuki’s ass was just that tempting to not rut against. It felt fucking amazing. Izuku was making these little noises, whining and practically crying, into the small space behind Katsuki’s ear, and Katsuki wanted to drown in them, wanted them to scratch the itch in his brain. He moved his head, just barely, completely against his own will, and Izuku took that as an invitation, biting and licking and teasing at Katsuki’s ear. And if that wasn’t just the best fucking thing to happen to him.
Well, it wasn’t.
Because now Katsuki’s own boner was straining against his zipper, aching to have even a fraction of the friction he was giving Izuku’s crotch. Izuku’s tongue was mind numbing. Tongues were used for eating, for fuck’s sake, it was a wet and nasty muscle that he never wanted anywhere near him, and yet his eyes closed as Izuku sucked lightly and timidly on his earlobe, still making these fucking whimpering sounds. He knew he was panting, shaky and shameless, and was thankful that the music was still blasting and not one person was focused on the little corner they had carved out for themselves, but he still felt so fucking pathetic, like a fucking loser for being this fucking lost to damn Deku.
“Kacchan,” Izuku nipped at the corner of his jaw, “Kacchan, please.” Katsuki didn’t have the fortitude to comply, too dazed and fucked out of his head to even register the request. “I can’t get out of the car hard, everyone will notice. We should stop.”
Stopping was out of the fucking question. “Then take care of it, shit nerd,” Katsuki tried to bite back, make it come off as pissed as Katsuki should have been. ‘Then stop humping me, sick bastard. When the hell did you think this was something we did?’ But that wasn’t the case, and Izuku, the #1 Bakugo Stalker, read him in a second. Could probably see how fucking lost Katsuki was, how he was right behind Izuku in this fucking game they were playing. God, he looked good like this. Flushed cheeks and lips bitten to hell from desperately keeping whatever noises he could under control.
That was enough instruction for Izuku, fucker did anything Katsuki asked (despite them both understanding Katsuki’s demand differently (there wasn’t a difference, but Katsuki had to pretend there was for his own fucking ego)) and took matters into his own hands.
Literally.
His grip on Katsuki’s waist became purposeful, manhandling Katsuki until his ass was slightly angled on his lap, his left leg now in between Izuku’s (shaking) thighs. The car was dark enough that, unless someone looked, it looked normal enough, but Katsuki still side-eyed the two on their left to make sure they weren’t paying attention. Once Izuku was satisfied with how he’d positioned Katsuki, he lowered his left hand to the curved spot where hip met thigh, splaying his crooked fingers into the dip of his thigh almost dangerously close to his dick. Katsuki was already losing it over that, and once he felt the right hand, the one furthest from possible wandering eyes and the one most covered by the blanket of night, grabbing and stroking at his right leg, he thought Glasses had actually managed to kill them and sent him straight to hell.
“Fuck,” Izuku grunted. Katsuki couldn’t have said it better himself. “Kacchan, fuck, can – can you -?”
Katsuki’s whole body had broken out into goosebumps, felt that fear and shock and numbness in the webbing of his fucking fingers, but he moved, as much as he could manage now that Izuku was back to peppering light kisses to his neck, but he knew he was fucking it up. His brain had completely liquified fucking forever ago and Izuku begging and saying his name over and over again was making his dick cry painfully. The embarrassment that was heating his whole body was fucking horrifying. This wasn’t Katsuki, he wasn’t part of the entire population who got all weak-kneed and so horny he couldn’t function. He was better than that, better than to let something like basic instincts fuck with his brain chemistry. He felt something foreign tugging in his throat, stinging his eyes. Well, that was that, now he could punch Izuku in the face and be done with this fucking freak show.
“Kacchan, can – can I, um, fuck, I’m just gonna,” his right hand slowly traced the inside of Katsuki’s thigh as it moved upwards, giving him time to reject the move (as if he’d be stupid enough for that), his breath hitching as it reached finally FINALLY to spread over Katsuki’s crotch, giving it the relief it had been begging for, relief Katsuki had never experienced, and it felt like he was seeing new fucking colors. He’d been missing out on THIS his whole life? Fuck, maybe he really had missed puberty.
Except it wasn’t for Katsuki’s benefit at all.
With the new leverage, Izuku started rolling his hips upwards. He was fucking up into Katsuki’s ass without a fucking care in the world about the fact that his hand was grinding down on his cock just to keep him in place rather than to help him get off. It was the hottest fucking thing in the world.
Izuku was still making the little noises, teasing Katsuki with a taste of how loud he could go given the space and privacy, and Katsuki listened, eyes closed around the stinging, and taking the sensual roll and the firm grip on his dick. Izuku nosed at his ear again, Katsuki turning into it encouragingly, chasing the high from earlier, and thank God Izuku got the hint quick and started nipping at his earlobe again, giving quick kisses to his neck in between to not overstimulate the skin.
It didn’t take long for Izuku’s controlled movement to become frantic, chasing his finish line while Katsuki happily took it. Katsuki wanted to see how he broke apart under it, wanted to memorize the look and sound. Katsuki’s brain had never wandered to this, never interested in it, but Izuku made it intoxicating, his obvious familiarity with this depravity something Katsuki wanted to engrave into his inner eyelids, but Izuku (the ever-greedy bastard) kept it to himself, tucking himself against Katsuki’s cheek when he tried to turn and face him, breathing heavy against the apple of his cheek and nose rubbing teasingly against the corner of Katsuki’s eye. And not a moment too soon, Iida turning the music down to announce they were pulling up on their destination.
The ice-cold bucket of reality washed on both of them at the same time. Izuku snatched his hands away from the dents he’d left on Katsuki’s shaky and sweaty skin. Only now that he wasn’t being held still did Katsuki realize how much he was shaking. He’d fought actual villains, the kinds that had torn down cities and actually killed people, and yet Izuku humping him like a dog was what was breaking him down. Fucking pathetic.
The second Frog Girl was off Bird Face, Katsuki was climbing over legs and bodies and almost falling flat on his face on the concrete once he was able to get his wobbly legs under him. He took some steading breathes, ignoring Shitty Hair and his concerned questions in favor of getting his mind to clear out and his dick to fucking disappear. Neither happened, so he let his best friend drape a heavy arm over his shoulders and guide him into the bustling dorm, not once looking back at the damn car and the fucking animal it caged inside.
Their classmates worked with a hive mind, gravitating towards the many coolers lining one of the walls of the mansion and passing around drinks until every hand was nursing a moist bottle or red solo cup. Katsuki had vaguely accepted the drink Kirishima had handed him, the brown liquid stinging his already sensitive eyes. Alcohol had been another thing society tried to make him feel he was missing out on, but it was something Katsuki was okay living without. Except scarred palms and heavy, wanting, breathing was haunting his conciseness. His mind wandered into memory lane for a SECOND and his whole body broke out into a thick layer of sweat and he’d rather not ruin the party with his homemade explosive so he downed the drink, surrounded by the cheering of his idiot parade, and gladly took the second drink Sero jovially offered him.
The night only seemed to drag on from there, his drinks going from beer dripping with condensation to mysterious liquids in solo cups, so he was unsure on how much he’d drunk by the time he was sprawled on the couch manually breathing. Katsuki didn’t like people, didn’t like mingling with them and all their annoying moods that he was somehow expected to accommodate for, but people watching while drunk was steading enough. Tapped into that cringey need of community within him without putting any work.
He watched the throng of people pulsing alongside the music, their individual noises turning into the backtrack for whatever heavy-bass song was thumping through the speakers. The floor was glistening with the drinks that were bumped and dislodged from tipsy hands, his own going down easier now that most of his taste buds had been burned by the hard liquor. But the alcohol hadn’t done its intended job.
There was a very distinct lack of green in the crowd, had been ever since he’d walked into the bustling party and fuck did that do something fucking awful to his ego. So what? Izuku was the type to hump and dump? (Not that Katsuki had made it any easier by running out the second the car stopped like a bat out of hell) At first, Katsuki had hungrily taken the drinks to try and drown whatever the hell had happened on the car drive here, but now the fuzziness flowing through his bloodstream was feeling cold, and he could only think of one person that could help him warm up.
On shaky legs Katsuki set out on a quest to find the fucking perv.
“Wow, man. You good?”
Katsuki blinked slowly at the red mass in front him, the low timbre of his voice familiar enough for Katsuki to reach out for it instinctively. The fresh air of the cold night was invigorating, slapping each individual nerve in his body on its stupid face and half waking up his senses. No idea how he’d managed to meander from living room to backyard but Katsuki was a survivalist, for fuck’s sake! The red mass turned into the red mass that was his best friend now leading him to the beach chairs filled with his idiots by the pool. But still, very annoying lack of green.
“Hey, where’s the nerd squad?” Katsuki was grateful for the sturdiness in his voice; didn’t need these fuckers getting any ammo on him.
“Nerd squad?” Sero asked as he passed whatever sour shit he was smoking to Denki. “I can only assume you’re asking for Midoriya’s crew?”
“Whatever, where the hell are they? Thought we came as a group.”
“Ain’t no way you are complaining about not having more people around,” Denki finished his sentence with some hacking coughs, Sero taking back the blunt with a smirk. “We’re in public, dude. We’re used to your rabid dog behavior with Midoriya but we don’t need you to embarrass us.”
“Fuck off,” Katsuki growled. Already he spent too much time with these fuckwads and not finding the green, freckled fuck. “Do you guys know where they are or can I leave now before I blow your asses up?”
“Oooh, some fireworks would be nice!” Mina jostled Kirishima, who had settled himself so his chest was pressed to her chest, as she sat up in excitement. “And I bet Aoyama would love to help!”
“Sparkles loves the fucking attention, ‘course he would.” Katsuki sent a glare to the rest of the backyard, making his way back to the building once nothing interesting caught his attention.
A heavy hand slapped his back, another sobering jolt (talking to the idiots was annoying but it had been centering enough), before the stocky smell of cologne and copious amounts of hairspray edged a headache. “Wait up, Bakubro!”
“Go back to your dumbasses, Shitty Hair.”
“Hey, they’re OUR dumbasses. I only get them in the divorce.” Katsuki would’ve kept walking but Kirishima spun him around a couple of feet away from the open double doors pouring out music, a safe blanket for quiet conversation. “What’s up with you? You’re not seriously fighting Midobro, right? ‘Cuz these parties are really cool, everyone is gonna be on your ass if you get us banned.”
This rambling Katsuki couldn’t stomach right now. Not when he was starving for a specific, very nerdy kind. “Shitty Hair, fuck off. Seriously.”
“Okay,” concerned red eyes tried to dig into him, “but if there’s something I could help with, then I should know.”
“This doesn’t concern you,” Katsuki said, no bite behind it. “Nerd been quiet too long, need to make sure trouble didn’t find him like it always fucking does.” A simple truth that Kirishima always took with a cheesy smile. “You know where they’re at, or you wasting my time?”
Finding the balcony Kirishima had told him about was fucking torture. Crowds flooded the hallways, horny couples (Katsuki was going to tell Iida about immediately) were making out in the stairwells, but eventually Katsuki stumbled onto the quiet top floor and found the only unlocked door. He poked his head in, his innocent eyes too useful to burn with the images of whatever he’d heard behind locked doors.
Katsuki almost chucked himself right off the balcony when he realized the relief that had flooded his chest when he’d spotted Half-and-Half’s candy cane ass. Not even under torture would he ever admit to being happy to see that fucker. That relief immediately went straight out his ass when the only green he saw was that awful puke green of Frog Girl. Fucking waste of time. He stepped into the room with the intention of raging and bitching (and whining, probably) about the only nerd he was hoping to see not being there when he felt a shy tug on his wrist.
He looked down, sad to see those evergreen eyes almost completely black in the darkness of the room.
“The fuck are you sitting down there for?” Katsuki grumbled, quietly closing the door behind him.
“Needed fresh air,” Izuku said, his lips quirked in a familiar way that made Katsuki ache.
“Of course you’re stupid enough to get fresh air by going IN a room.” Izuku’s snorted out a laugh. “Well, move over fucker, or you want me to sit on your lap again?”
Both of them were taken completely by surprise at whatever the fuck came out of Katsuki’s mouth, frozen in place playing the chicken game. Another reason to add for his already long list on avoiding drinking, ‘Makes talking out of your ass easy’. And, like always, Izuku broke first.
A groan, straight from Izuku’s fucking diaphragm, filled the empty space as he buried his face into his hands. The alcohol was still working wonders on Katsuki, making a giggle escape him as he moved to sit on Izuku’s left side. Even Izuku, Bakugo Extraordinaire, seemed surprised, lifting a puzzled look at Katsuki (who would blame the drinks on FORCING him to press himself firmly against him). Katsuki smirked down at Izuku, who was still trying desperately to hide the raging blush that Katsuki could see better now that they were closer. Definitely feeling warmer now.
“Now you getting shy on me?” He was trying to bump their shoulders together but they were already pressed so tight, so they swayed in their sitting position. “That why you were avoiding me?”
Izuku heaved a heavy sigh, resigned to Katsuki’s line of questioning. Always puddy in his hands. “Survival instincts, I guess.”
Katsuki snorted, resting his forearms on his knees as he relaxed his head against the cool wall. “Or you being a pussy, whatever you wanna call it.”
“I didn’t know what to call it,” Izuku looked down at his lap, his nails scratching at the cuticles of his crooked fingers, “didn’t think you running away like your ass was on fire was a good sign, though. Better to steer clear.”
“I didn’t run, firstly. I never fucking run. And don’t talk about my ass being on fire when you could feel it damn well wasn’t.”
Katsuki didn’t know how to do any of this, never had a care for it, but teasing Izuku was familiar. Poking and teasing until he got those freckled cheeks to break out in that nice red shade was routine. Redirecting it towards something more vulgar, something close to flirting, was a muscle strain, as if he’d trained with some extra weight for extra reps, but not unwelcome. Maybe he could possibly see the tiny bit of appeal to drinking.
“I’m so sorry, Kacchan.” It was quiet, just shy of embarrassed. Enough to tug at Katsuki’s tiny and walled up heartstrings. “I’m- holy shit, Kacchan. I’m so fucking sorry. I don’t know – I have no idea why I did that. I don’t – I’m not that guy. I’ve never done anything like that, it’s like a fucking, a thing, came over me. It’s not an excuse, shit that’s not what I’m trying to say.”
“Relax.” It was an immediate salve over Izuku. Katsuki had felt like pray in a bear trap in that car, completely at the will of the animal that Izuku also acknowledged had taken over him. Now though, seeing the mumbling (cute, familiar, fucking embarrassing) green mess, he was able to breathe, look at it in a new light. It hadn’t been this dangerous fucking creature that had been ready to eat Katsuki alive, just Deku. “Don’t worry about it, not like you fucking broke me.”
Izuku still couldn’t meet his eyes, despite having lost a considerable amount of tension from his shoulders. “Still, Kacchan, that was fucked up. I’m really sorry.”
“Fucking, whatever. What, are we gonna talk about this until I decide to kill us both just to end the conversation?”
“There should be some conversation!”
“Only if you wanna make it weird!”
“Are you trying to say that wasn’t weird?”
“Weird as hell when you hump a guy with no warning! Just,” Katsuki glanced at the group still sitting on the balcony, none of them paying Katsuki and Izuku any attention despite their loud conversation, “next time, give a guy a warning.”
Something was swimming in the doe eyes looking back at him that Katsuki couldn’t recognize. Katsuki had gotten better at admitting when he was wrong, but it was a bitter pill to swallow. Like right now, swallowing under those predatory eyes felt like he was moving without permission. “Next time?” Katsuki was a fucking idiot for thinking it was just Deku.
He took in a breath, cussed himself out internally when he felt it rattle against his bones so audibly, and tried to keep his gaze fixed on Izuku’s. Because he doesn’t fucking run.
“That wasn’t a fucking invitation, don’t get your freaky thoughts twisted.” It came out like gravel scrapping against his throat. Izuku huffed out a laugh, still zeroed in to Katsuki like he always was (Bakugo Glazer Hall of Famer (he was going to strangle Denki for ever learning how to speak)). The alcohol was still swimming in his veins, cracking open the door he kept all his useless emotions under check, so really it was its fault when a rush of panic thumped through his heart. “But don’t be asking your group of freaks either. No telling if they’ll be as nice as me when manhandled out of nowhere.”
“If this is you nice, I hope I’m never on your bad side.”
“You wouldn’t be able to handle my bad side.”
“Try me.” The cockiness dripping from those two simple words stirred his lower gut, annoyingly reawakening his dick. This fucker had never even stirred outside of morning wood but now it wanted to show off and do it twice in as many hours? Bitch ass. “And don’t worry, no one I’d rather ask.”
Another hard lump he had to swallow. “Fuck, how do you do this so easy?”
“Do what?”
Fuck. That had been an inside thought his loose tongue had failed to reel in. But something about the dark of the room, of the vibrating floor from the bass coming from downstairs, of another bubble they had made for themselves, made him feel… safe. Or, unguarded.
“This… whole thing.” Izuku scrunched his brows in question, his bunny nose twitching. Deceiving fuck, a wolf hiding in rabbit skin. “What? You have a lot of experience throwing it around?”
“Throwing it around?” Izuku asked, scandalized. “I told you, I’m not that kind of guy!”
“So I just happened to get caught on the wrong side of the rock-hard stick?”
Izuku had so many quirks it was hard to keep up but Katsuki thought maybe this is what Danger Sense felt like. He felt the shift before he saw what it did to Izuku’s usually soft features, something more solid taking over. A look that made goosebumps break out on his arms and make him feel jittery. “You really think I’d do that with anyone else?”
“… You wouldn’t?” He tried for disbelieving, that he didn’t buy the innocence Izuku was trying to sell, but even to Katsuki’s own ears he could hear the neediness behind it. It sounded so foreign to him, couldn’t recognize this weak thing he turned into sitting next to Izuku.
Izuku must’ve noticed it, and like the fucking animal he apparently was, pounced on it. He leaned in, lidded eyes giving him a once over like damn sin itself. “Not really about what I’d do to someone else,” a sneaky, heavy palm weighed his right leg down, stroking the inside of his knee in lazy circles, “just about what I want to do to you.”
That same freezing spell washed over him, as if Half-and-Half had gotten his dirty hands on him. Speaking of. “Hey, your fucking nerds are right there. You get a kick outta doing this shit in public?” It came out in the same breath, the panic making his voice high and squeaky and fucking pathetic.
A sharp smile, his canines a threat in and of themselves. “Makes it exciting, doesn’t it?” Their cheeks brushed each other, Katsuki mildly surprised he didn’t melt the skin off Izuku’s face with how hot his face was burning. A husky whisper, something Katsuki never would’ve imagined he’d find so fucking addicting, brushed against his ear. “Kissing Kacchan is pretty fucking exciting all on its own, though.”
Katsuki let his shaky breathes wash over Izuku’s neck unrestrained, as if he had a fucking choice. Once again, he was in that fucking bear trap, not knowing what to do or even remembering how to fucking move.
Izuku’s left hand was an anchoring weight on his knee (or a leash to keep him in place, he hadn’t decided), while the right hand crept up and up and up until it nuzzled nice and authoritative over his stiff, still clothed cock. No idea why Katsuki had even cared about the Nerd Squad a couple feet away when right now, the only two people that ever existed were Deku and Kacchan.
His right ear seemed to be Izuku’s favorite snack, nibbling and licking the shell of it as his hand expertly pushed and rubbed and squeezed.
“Uh, ah,” Katsuki tried, really fucking tried, but his tongue was lead in his mouth. His eyes were shut tight but felt the laugh Izuku huffed against his jaw as he moved down to lick at his pulse point.
“Kacchan’s so sweet like this,” Izuku said, those canines nipping at the thin skin over his jaw, “tastes sweet too.”
“F-fuck off.” Even those simple words took so much fucking effort.
A squeeze that even unexperienced Katsuki could tell was too tight to be meant to feel good and a hiss escaped Katsuki’s clamped mouth. “Stop, don’t ruin it, you were being so nice.” Izuku pulled back and an infuriating and pathetic ass whine escaped his quivering chest. “And just when I was thinking of giving you the wrong end of my rock-hard stick again.”
Not having Izuku’s panting and licking pressing down on his neck anymore was annoying and left him cold but also let him get a lungful of air. His tongue lost some of its weight, the words still coming out through clenched teeth. “Like I fucking asked for it.”
“Would you?” Izuku was ready to eat him alive (and maybe Katsuki would let him (what the fuck??)). “Would you ask for it?” The rubbing was giving him some friction burn. Katsuki had been burning his whole life, but not like this. Nothing burned like this. “Kacchan, oh fuck, Kacchan, would you beg for it?”
When did this fucker get so mouthy?
And when the fuck did Katsuki struggle this damn much to keep up with the nerd?
“Deku-uh – “ He couldn’t focus, not when Izuku’s pupils were blown out to high hell, not when Izuku’s warm fingers kept running along the outline of his cock.
“I want to be nice, since you were so sweet in the car for me.” The words were syrup trickling into his chest. “Can I be nice to you, Kacchan?” His hand had started playing with the button of his jeans, leaning in until their breaths intermingled and mixed –.
A booming laugh snapped them back to their bodies. Katsuki pulled away as if burned, whipping his head towards the group still huddled close on the balcony but they were still blissfully unaware of the two. Katsuki needed more, though. He needed more than to hide in a corner and steal some of Izuku’s heated touches for himself. Katsuki had improved since coming to U.A. but he was still irrevocably selfish when it came to Izuku. ‘Keep your eyes on me, Deku you dweeb!’ and all that.
With a growl Katsuki abruptly stood, Izuku flinching away from swinging limbs still woozy from the foreign liquid invading his veins and yanked the door open to stomp his way out. He stalked down the hallway as he glared at laughing and chatting groups until his eyes landed on an open door at the edge of the dance floor that the living room had turned into. The light flashed on and illuminated the unoccupied bathroom. Katsuki jumped onto the counter and glared at the still open door, waiting. He didn’t have to wait long.
Izuku’s bulky form haunted the doorway anxiously, and when Katsuki didn’t tell him to fuck off, he cautiously stepped in and closed the door, a quiet click of the lock echoing through the walls, leaning against it as far away from Katsuki as possible. As if he could blame the guy.
“I wasn’t running,” Katsuki clarified with fiery indignation, “I just don’t have the same kink as you do to fuck in public.”
Izuku burned red from Adam’s apple to the roots under the green mess of curls. “What?! I - I don’t! What are you - It’s not like I’m doing it on purpose!”
“Yeah, whatever you say,” Katsuki said with a smirk.
Izuku fought against his own smile. He looked down at the ground shyly, so fucking cute, still leaning against the door. “Kind of hard to focus on anything else when I’d rather focus on you.”
It was Katsuki’s turn to blush furiously. He gripped the counter he was sitting on to keep from shaking. “Don’t say stupid shit like that, you sound like an idiot.” He put as much bite into it as he could. It was a tried-and-true method for Katsuki; to hide emotions he had no need for underneath harsh words so he could push anyone too close to observe them away and they could stay safely tucked inside his chest. But Izuku was a stubborn bastard with just as much experience dealing with Katsuki as Katsuki himself. So Katsuki didn’t flinch away when Izuku crowded against him slowly, placing his scarred hands on either side of Katsuki’s on the cool marble counter. He didn’t look away from the familiar determined look solidifying the intense green eyes. It was expected, it was familiar.
“Would you rather me tell you that I don’t care if anyone sees me fucking you as long as I get to fuck you?”
The wind was snatched, ripped, fucking obliterated from his goddamn lungs.
Katsuki froze, again, and fucking hell that was the most frustrating part. He felt that same heaviness in his throat and the frustration of feeling this gaping hole of inexperience in his psyche made his eyes sting and wait, is there an earthquake or is he shaking again?
“Kacchan?” It was so fucking soft Katsuki wanted to punch it until it sharpened around the edges.
“Fuck off,” he snarled and it must’ve been convincing enough since Izuku had started to back away but Katsuki’s hand swung out on its own volition, tight grip against Izuku’s t-shirt before he could get too far.
“Um…” Izuku said in a wobbly voice. Everything about Izuku was wobbly, and squiggly, and squirmy. He was so fucking squirmy. “Uh, should I – do you want me to leave?”
“Does it fucking look like I do?” Katsuki tightened his grip pointedly. “Fuck, it’s like you’re two different fucking people.”
“Do you want either one here now?”
Katsuki, despite that foreign feeling of fear, laughed, something low but something that still pulled on Izuku’s trembling lips until he was poorly mimicking Katsuki’s own smile. “Unfortunately.” He knew he was being difficult and he could see Izuku trying to keep up with him. But, thankfully, Katsuki didn’t have as hard a time talking to Izuku anymore. A lot of things were easier with Izuku now. “I – fuck. I…” Izuku stared back, so fucking patient and with eyes just drinking Katsuki in. “I don’t know what the fuck to do,” he whispered. It still felt shameful, even if just a little, when admitting.
If there’s a cool and suave way of saying ‘Hey, I’ve never done anything like this, never had any interest in touching my own dick, but if you don’t do it I might go homicidal’, type it in the comments ASAP because Katsuki needs to know right now.
“It’s okay Kacchan,” Izuku smiled, something Katsuki had always assumed was innocent and nerdy but when paired with wandering hands slotting against his waist possessively, it left Katsuki panting, “you don’t have to do anything.” A part of him still wanted to argue, engrained into his very DNA to fight against Deku. “Just be a good boy and listen.”
Well.
He’s not about to be bad at something, alright?
He barred his teeth, pathetically clinging to the façade of reluctance, but Izuku was unfazed. Fucker. Katsuki’s fingers were digging into the underside of the countertop, his legs crossed at the ankle reluctantly, glaring into Izuku’s bug eyes. They both knew it was bullshit but it was somewhat nice that Izuku was playing along. His wide palms trailed slowly from Katsuki’s hips that had broken out in goosebumps down his trembling thighs. Izuku was studying him, watching his every move like he always seemed to be, before he rested his hands on Katsuki’s knees, squeezing but stilling his movements.
Katsuki wanted to growl. Where the hell was the guy from the car, that was groping Katsuki unashamed? The guy ready to jump him in a room full of their classmates? What, did he think Katsuki was that freaked by it? Did he think Katsuki was weak?!
“Kacchan.” Izuku leaned in, lips ghosting against Katsuki’s. They were tempting, so fucking close, but Izuku refused to move closer, and like hell was Katsuki chasing.
Frustrating little shit. “Deku, stop being a little –.”
The hands that had just been soothingly rubbing circles against his thighs gripped the underside of his knees and pried them open. Izuku pulled him forward with the new handle he had on Katsuki’s legs to the edge of the counter, a gasp escaping him when he felt his crotch press against Izuku’s.
“Wrap your legs around me.”
Only reason Katsuki did was because his survival instincts kicked in. Definitely a perk, though, when their crotches rubbed together when he did. He felt the scars against his abdomen before his brain even logged back in from the friction on his half-hard dick, shallow breathes filling the small space between their lips. Izuku roamed the skin slowly, mapping the area greedily, eyes trying to eat Katsuki alive. Katsuki squeezed his legs on reflex when fingers grazed his nipples as Izuku continued his slow exploration.
Izuku, being as Katsuki obsessed as he was (who could blame him, poor thing), immediately noticed.
“Can I lift your shirt?” Izuku asked softly, still refusing to kiss Katsuki with his chapped ass lips.
“What happened to just listening?” Katsuki was shaking again, the adrenaline raging through him and making his voice crack and sound fucking desperate. What the fuck was Izuku doing to him?
Izuku laughed, this airy thing that made Katsuki scoot closer to the edge of the counter and harder against Izuku. Fucker wiped a thump purposefully against his nipple and this time Katsuki couldn’t bite down the embarrassing whine. “Wanted to hear you, Kacchan.” He pinched it with a sharp smile as Katsuki squirmed under the mean touch. “You sound so cute when you’re being sweet.”
Katsuki growled something close to ‘yeah hurry up’ and Izuku spared a hand, the other still massaging his pec like a fucking perv, to lift the shirt. Katsuki went to lift his arms but the shirt didn’t make it past his chin, Izuku rubbing the cotton against his bottom lip until Katsuki got the message and bit into the material.
He knew his chest was flushed red, the embarrassment of being splayed out like a whore for none other than Deku making his body break out into a sweat. But it was hard to remember to care when Izuku’s rough palms gently skittered over his muscles, a mumbled but clear “Pretty Kacchan” making Katsuki arch his back under the praise.
“Yeah, like that baby, keep it like that.”
… Ayo, what the fuck?
Izuku guided Katsuki by pressing a calloused hand to the small of his back so Katsuki would keep his back arched and his chest puffed out high. Katsuki might’ve bit out something stupid and mean but a loud moan filled the quiet of the bathroom that not even the booming music could dampen as Izuku latched onto a nipple and sucked. It was bruising, Katsuki reaching for green curls and gripped them tightly in his fist, but didn’t dare pull him away. He salivated into his shirt and let out another filthy moan when gentle licks, as if Izuku was making out with his tit, surrounded his nipple and kitten kisses lavished the rest of his pec with attention.
“You’re so sweet, Kacchan.” A kiss to his collarbone. “You’re being so good for me.” A nip to his nipple, his hips finding purchase against Izuku’s own clothed and stiff cock. “Is there anything Kacchan wants me to do?”
Always considerate, always making sure to put Katsuki first. Annoying as shit. He should lash out, should tell Izuku to fucking grow a pair and take what he so fucking clearly wanted. Why was it always up to Katsuki to call the shots? Izuku couldn’t fucking think for himself? Katsuki should really tell him off, tell him to stop being a little bitch and take the damn lead.
“Please, Izuku, don’t stop. Anything, anything you want. Just keep, aah, keep going.”
Close enough.
Izuku’s teeth dug into his own lower lip as he tried to restrain his own groan when he met Katsuki in the middle and rolled his hips firmly against him. What Katsuki wouldn’t fucking give to feel the canines against his lips. “Dangerous, Kacchan.” The hand that had still been pressed to his spine dipped lower and lower until his fingers inched inside his jean’s waistband and traced the dip of his ass crack. “I’m a little selfish when it comes to you.” His shirt had fallen back down his chest when Katsuki had opened his stupid mouth to beg but Izuku didn’t let that stop his hands from roaming the expanse of skin. “If I take a little bit, I’m going to want the whole damn thing.”
Katsuki shivered. He chucked his shirt to the other side of the bathroom, his hands carding desperately through Izuku’s unruly hair. “I thought you were gonna be nice to me.” Green eyes were eclipsed with how blown up his pupils were. This whole desperate thing looked divine on Izuku. “Take what you want, nerd.” He was still scared shitless; this confidence was an adrenaline rush that would make him crash and burn if Izuku decided to back off or dilute himself for Katsuki’s sake. With the last bit of conviction he had he leaned forward and left a chaste and fucking virgin ass kiss on the corner of Izuku’s lips. “I’m all yours, Izuku. Be fucking selfish.”
Katsuki’s leaking cock was free from his jeans within the blink of an eye. With how debauched and downright starving Izuku looked, his stroking was slow and deliberate, his eyes never looking away from Katsuki. Izuku’s big heart was one of his best and worst features and if Izuku stopped to ask Katsuki one more fucking time literally anything Katsuki would probably cry. So he looked the nerd right in the eye as he was jerked off as his jaw fell open and moan and whimper and plea escaped him, his hands tensing and relaxing against Izuku’s nape.
Masturbating had always been about doing it to get it done. A necessary evil. Fucking whatever, he was a prude. But Izuku made it an art. He twisted his hand as he stroked upwards, swiping his thumb against his leaking tip and gently rolling his fist back down. The friction was a slow burn Katsuki panted for. Nothing burned like this. Izuku was breathing heavy into his mouth and Katsuki drunk it in.
Izuku was meticulous, studying every twitch and every hitch of his breath, and Katsuki loved the scrutiny. Loved that he was on display and was being adored so completely. It was intoxicating. Katsuki wanted to shower Izuku with the same attention.
He clumsily reached for Izuku’s shorts but Izuku pulled away, huffing out a laugh.
“What the fuck,” Katsuki whined, petulant and needy.
“You’re so fucking pretty Kacchan. I want to keep you like this for a little longer.” Katsuki didn’t have a little longer in him. He was ready to argue, the complaint on the tip of his tongue, but Izuku had latched onto the pulse point under his jaw and bit into the thin skin, licking it apologetically when Katsuki hissed in pain, and sucked the mark as his hand continued its dry friction against his dick. It was most likely the inexperience, or the fact that Izuku had gone back to whispering praises into his neck and chest as he peppered kisses to whatever skin he could reach, or maybe Izuku was just that fucking good at handling his dick, but Katsuki REALLY didn’t have a little longer in him.
With a groan, his hands went back to gripping Izuku’s hair as Katsuki came into his fist, that annoying and familiar sting coming back to his eyes. He was breathing hard and when he felt Izuku slow to a stop at the tip, he took a second to steady himself. Izuku, being the motherfucker that he’s so famous for being, only gave him a second to steady himself before he was rolling his cum down his dick to continue the now torturous stroking.
“Izuku, fuck, hold on,” Katsuki squirmed under the overstimulation but Izuku was entranced, watching his own hand go up and down Katsuki’s sensitive dick. The dry stroking had been teeth-gritting and pulled painfully but Katsuki had loved the sting. But feeling his own cum coating his dick was something fucking else. He was moaning, almost crying, but Izuku was gentle, aware of his sensitivity.
“Kacchan?” He twisted his hand at the tip and Katsuki cried out, high pitched and pitiful. “Do you want to stop?”
“Izuku, fuck!”
“Or can you keep being a good boy for me?”
Kind of a no-brainer.
Katsuki bit his lip to stop another cry from escaping him as Izuku pinched the tip with his fist, squeezing his cum in place. “Take your pants off for me, Kacchan.”
Maybe when his horny brain sobers up would Katsuki find it within himself to be embarrassed about how fast he kicked his pants off. But Izuku hissed out a ‘Fuck baby, so good for me’, so really nothing else fucking mattered and now Katsuki was naked sitting on a cool counter as Izuku’s fist was still covered in his cum.
“I’ll be gentle, okay?” Katsuki made a noise of question but wasn’t left wondering for long before Izuku’s cum-covered fingers found the rim of his hole and he was whining and shuddering under the featherlight touch. The cool coat was nerve wracking and when he felt a crooked digit trying to squeeze inside, Katsuki sharply gasped. Izuku immediately stilled and yeah, fuck that.
Katsuki grit his teeth together as he tried to roll his hips to suck the finger deeper. Katsuki wasn’t a damn quitter. “Stop being so fucking gentle, fucker. Think you’re gonna break me?”
“God, I hope so.”
Izuku traced the puckered skin slowly, one lazy circle around it, before finally sinking into the tight heat. Katsuki shriveled into himself when the fire of the stretch flickered against his whole body. For one dumbass moment Katsuki thought that’d be it, but then Izuku was pulling out just as slowly as he’d pushed in, and then he was pumping Katsuki carefully, really relishing in all the whorish noises Katsuki was practically screaming out.
“Gonna do another finger, okay baby?”
“Fuck, yes!” He wanted to feel the fullness, wanted to feel only Izuku. No need for air or insecurities when his lungs could be pushed aside and make even more room for Izuku.
Izuku sunk his teeth into his collarbone, sucking the bite again. Was Katsuki just a chew toy for the nerd? His softening dick twitched in interest at the thought. “Such a good boy, Kacchan. You’re so sweet, so nice for me.” When he licked a bruise that had formed on his chest that Katsuki hadn’t even noticed, Izuku looked up with hooded eyes as he kissed his nipple so sweetly. “But I love my Kacchan mean and rude.”
It was torture. Izuku was slow, methodical, opening Katsuki, wringing out every humiliating noise Katsuki didn’t know he could even make an hour ago out of him. His dick was standing back at attention and weeping for contact, for literally Izuku to just fucking look at it, but Izuku couldn’t be bothered. He was three fingers deep and not even the ceiling caving in would break his concentration.
“Izuku, come on,” Katsuki pulled Izuku closer, hooking his legs around his waist again, “I need you to fuck me, I’m ready, I don’t fucking care if you break me, so come on –.”
“What?”
Izuku’s eyes were feral, and some of the earlier nerves threatened Katsuki’s psyche again, but Izuku, this god of a man, was shaking from how fucking badly he wanted Katsuki, from the sheer will power to hold back for Katsuki’s sake, and that was breaking down any walls Katsuki could’ve possibly still had.
Katsuki sank his teeth into the fat of Izuku’s bottom lip. Izuku hissed at the harshness but Katsuki was a quick learner and licked the sensitive spot, letting their lips slot together softly, so unlike everything else they were doing. Their tongues shyly peaked into the other’s mouths, quiet moans vibrating from one’s throat to the others’, heated and intimate in a way anything else they’d done and were currently doing couldn’t even compare to. It was distracting, but not enough.
Katsuki pulled back, spoke into Izuku’s open mouth. “I need you, Izuku. You haven’t gotten that through your thick head yet?” He hoped its enormity was obvious, that Izuku saw the way the statement broke from the four walls of the bathroom. I need you, Izuku. Have needed you since the moment I thought I hated you. You’re the only person I’d fall for so I need you to catch me.
They were kissing again but it was a spiderweb of a kiss. Katsuki’s hands were shaking were they held Izuku’s jaw, trying so fucking desperately to keep himself together. Izuku wasn’t fairing much better either, his own distraught whines coating Katsuki’s insides as his fingers continued to gently, so fucking caring, continued to stroke the inside of his aching hole. They were already at this point, literally knuckle deep, but they were both terrified of feeling this crumble in their hands so they were careful, they were caring.
It was Katsuki and Izuku.
Izuku pulled away which was a terrible fucking idea when Katsuki’s emotions were laid out this raw and needy. It felt like a chasm that he couldn’t imagine ever being able to fix.
“Izu-Ooh!”
Katsuki had been burning his whole life, but not like this. Nothing burned like this.
“Kacchan, holy shit.” Inch by inch, Izuku pushed in. “I-I can’t – are you okay? Is this okay?” Katsuki was shaking but his ankles didn’t waver from where they were locked against Izuku’s back. “Kacchan, fuck, holy shit, Kacchan…” The lubrication of the cum was different than it had been on his cock. Izuku was ripping into him and Katsuki already knew he wouldn’t be able to walk straight the rest of the night. Next time, lube was definitely gonna be on his shopping list. “You feel so fucking good.”
Deep breathes in and out (yeah, it was more like hyperventilating but fucking whatever). Izuku’s grip on his waist was a lifeline, his evergreen eyes concerned and yet so wide and skirting all over his face to catalogue every twitch and wince from Katsuki. He was panting right into Izuku’s mouth, his whole face scrunched up as he tried to calm his shaking nerves.
“Kacchan?”
“Shut the fuck up,” Katsuki hissed. His tailbone was aching, his asshole was being torn apart, and the music had turned into basic ass radio hits. Literally fucking heaven.
Like the freaky little mind reader he was, the nerd reached for the hand towel hanging over the toilet and effortlessly lifted Katsuki up to place the towel under him. Katsuki moaned as the dick with a fucking interior design diploma shifted even deeper, Izuku cooing in an effort to comfort him. He was being peppered with soft kisses and even though they were still as possible Katsuki was whining desperately.
“You’re doing so good, baby.” Izuku kissed him slowly and passionately while Katsuki could only take it slack-jawed and feeling so full he could only breathe whatever Izuku exhaled into him. His sides were warmed as calloused hands rubbed from thighs to ribs as if that could stop Katsuki’s shaking. This is it, right? This is sex, they’re done now? “You can keep being good for me, right, Kacchan? Come on baby, keep being sweet for me.”
A controlled thrust, barely anything, Izuku staring him down with a ferocity he could feel dig into him. Does he have to use the ‘stuck in a bear trap’ metaphor again or are we on the same page? Katsuki crept his hands under Izuku’s t-shirt to hold the freckly and toned stomach underneath and locked his legs around the wide waist even tighter.
“I’m your good boy, ‘Zuku.”
The dopey and genuine smile that Katsuki had seen so often before was breathtaking. The dick piledriving his lungs into his fucking throat had nothing to do with it.
Through the initial first thrusts Katsuki could do nothing but cling for dear life and Izuku didn’t even seem to care. Once some air was able to sneak its way into Katsuki, his whines from oversensitivity reverberated throughout the bathroom, their skin slapping loudly and lewdly, Izuku’s ridiculous red shoes squeaking against the floor. The loudest thing in the room was still Izuku’s praises. Or maybe Katsuki was wired to seek them out. Whatever.
“Fuck baby – Kacchan, ah AH – this is unbelievable.” Katsuki clutched onto green curls and Izuku took that as his cue to lean back down to mouth over Katsuki’s Adam’s apple. “You’re so, so perfect baby. You feel so good. You’re so good Kacchan, so fucking good.” Another bruising kiss to the column of his throat.
“Izuku!” He grunted through gritted teeth.
“Come on Kacchan, be my good boy.” Teeth scrap against his jawline.
“Fuck off- Ah!” He yanked Izuku back to glare at those lust-filled eyes.
Izuku smirked and fuck he wanted to bite it off. “Naughty Kacchan.” And the fucker, the motherfucker, stopped completely, gripping Katsuki’s waist tight and effectively stilling any enticing hip roll Katsuki attempted. The mean smirk slipped into a pout that was dorky Deku down to the sparkly green eyes that were always trained on Katsuki. Always on Kacchan. “Please?”
He was more gentle, letting Katsuki feel every inch. “I’m not naughty,” Katsuki panted out. He locked his hands at his nape as he leaned back to shift Izuku’s angle in him, chasing that ghost of a touch his dick had made offhandedly inside him. His cock was painfully hard again so they had to speed this the fuck up.
“We’ll see about that.”
Even, slow strokes to the spot that had Katsuki seeing stars. Katsuki cried out and Izuku fucking giggled as he picked up the pace, kneading more and more desperate whines out of him until his ass was smacking aggressively against Izuku’s sturdy hips. If Katsuki tried to bite down on a moan Izuku would immediately stop and suck harshly on a nipple, biting the pec around it until a multitude of blooming bruises sprung up. He palmed the precum that had pearled on his cock and Katsuki was a squirmy mess.
“Izuku, fuck, Izuku!” He cried out into the room.
“So pretty. My Kacchan is so pretty and sweet. My good boy, I love you so much, fuck, Kacchan!”
Izuku stroked him until he was spasming and cumming onto his stomach and bruised chest. As considerate as Izuku was 99% of the time, this apparently didn’t qualify. The same stinging pain to his eyes overcame Katsuki but he was being fucked out of his mind so he didn’t have anything left in him to fight it. So Katsuki started crying as Izuku grunted and moaned and continued to sing his praises as he chased his own high, again, and Katsuki was his only way to get it.
It was a searing kiss that only shook even more wrecked sobs out of Katsuki as Izuku thrust as deep as he could so he could paint as much of Katsuki’s insides as he could.
The calm down felt hours long. They both whined at the loss as Izuku’s cock softened enough to slip out and the loss was fucking brutal. The tears that had dried up were coated with new ones and these ones Izuku did notice.
“Kacchan? Are- are you okay? Hey…” He palmed at Katsuki’s cheek tenderly, his brows scrunched up real ugly.
Katsuki tsked as he reached his own hand to the wrinkles on the freckled forehead. “Tell you not to do that, nerd.”
“Can’t help it when I’m worried about you, Kacchan.”
He was still so raw with emotion, literally stripped naked in front of Izuku. “… Because you love me?”
Izuku kissed his cheek once, twice, until his whole face was being attacked with kisses. He hissed as his legs were lowered back down but Izuku was there to rub his thighs to soothe the ache as he continued to whisper sweet everything’s to Katsuki. “Are you kidding? I love you so much, how have you not noticed? Basically tell you any chance I get.”
Katsuki let out a wet chuckle. “You’ve been saying that stupid shit since we were snot-nosed kids. What you trying to say?”
Izuku had turned the faucet on to soak the towel Katsuki had been sitting on and had soothingly started rubbing the moist cloth on his sensitive hole. “You’re a smart guy.” A tender kiss to his wet cheek. “You can figure out.”
He already knew. Knew it from when Izuku would propose on the sandbox or almost destroyed himself for Katsuki’s sake. Bigger conversation for another time, though. Not when Katsuki was sore from getting buttfucked in the bathroom at a party. “Yeah, whatever. Give me my clothes back nerd, it’s fucking cold in here.”
Izuku laughed, something fond and soft shining in his eyes, so he couldn’t help but smile into the kiss Izuku snuck in before retrieving his various pieces of clothing from around the small room. With some protests and warning hisses Katsuki tried to scare Izuku away but at the end he gave up fighting and allowed the nerd to help him get dressed. He did swat his hands away when he started fucking with his spikes and shit.
“Deku, what the ACTUAL fuck?”
His neck was covered with purple markings and Katsuki could fucking swear that he could read DEKU written with them. Fucker had collared him. Through the mirror Katsuki saw Izuku looking bashfully down at his feet with his strawberry face twisted up and squirmy. Always so squirmy. Cute ass nerd.
He heaved a dramatic and heavy sigh as he turned around to face Izuku straight on and was immediately salty as hell when he saw not even a single mark on him. It was a quick remedy, Izuku let Katsuki tilt his chin to the side with a simple hook under his chin easily enough. His breath hitched as Katsuki smirked against the skin before taking a gentle bite before suckling on the thin skin under his jaw. The rewarding matching bruise stirred his stomach nicely. All those horny hormones he’d missed all those years were really fucking show out now, weren’t they?
“You’re lucky I love my nerds possessive.” Izuku’s eyes got watery in a very Deku trademarked way but the bathroom was getting stuffy, they were playing the music he knew Izuku went nuts for and he really needed a drink. “Ready to go back out there, Deku? ‘Cuz your nerds are probably going crazy out there.”
“Uh, yeah. We should probably go.” Katsuki started to shamefully limp towards the door but Izuku’s lips were on his before he got too far. It was a new taste Katsuki was definitely going to indulge in if his life depends on it. “Sorry, just needed one for the road. Um, wait here, I’ll check to make sure the coast is clear?”
“Hurry the hell up, I’m thirsty and need to sit somewhere soft.”
Izuku poked his head out, taking a couple of seconds to scope out the scene before he closed the door quietly. He flashed Katsuki with a squiggly smile that reeked of trouble. “So, uh, it seems that maybe a couple people might know we’re in here.”
Katsuki huffed out laugh. He was going to be parading around the party with Izuku’s damn claim on him anyway. “Not like we were being quiet, either.” Izuku still looked shameful, couldn’t even face Katsuki. “Next time, I’ll take you somewhere nice where you can make me cry and we’re not listening to fucking boybands in the background the entire damn time.”
Immediately Izuku perked up like a puppy hearing its favorite word. “Next time?”
A kiss to the cheek. A promise for a different future. “Next time.”
He reached for the door again, Izuku grumbling something that sounded like an apology or whatever the fuck.
‘A couple people.’ Katsuki was going to beat the fuck out of Izuku with a dictionary until he fucking learns the meaning of a couple.
The loudest cheering he’s ever fucking heard almost burst his eardrums. He didn’t want to believe the entire fucking party had been hearing him begging Izuku to fuck him harder but at the front of the jeering group was HIS group of idiots that were laughing hysterically and that made it infinitely worse. Cat calls, wolf whistles, and literally a dozen more things were shouted at him that made his palms spark dangerously.
“Bakugo! What the actual fuck?!” Heavy arms were thrown over him as his idiots got him in a group hug (their way of protecting him from prying eyes (kind of sweet or whatever)). “THAT’S why you were looking for him earlier? You slut!”
Whatever threats Katsuki wanted to aim at them was drowned out when the gathered crowd started cheering again when Izuku, beet fucking red, stepped out of the bathroom. He looked even more out of it than Katsuki felt. Enough to kick his ass into action.
He weaved through his friends to grasp Izuku’s hand firmly in his and steered them past the loud and annoying ass extras still watching them like zoo animals.
If Izuku wanted to say another stupid apology or to try to crawl into a hole, Katsuki didn’t let him get too far into that thinking, shoving a solo cup into his hand before dragging him to one of the couches pushed against the wall. Everyone already knew their dirty deeds, saw it on the branding on his neck, so Katsuki had no reservations about cuddling up close to a shy and nervous Izuku. He really did love the nerd.
“Fucking shit show.”
“Kacchan, I’m so sorry, I shouldn’t have –.”
“But if that’s what I get for being a good boy, can’t fucking wait to see what you do to me when I’m a bad boy.”
“Kacchan!”
